I'd like to make sure my thinking is right on this problem and to see what the next step would be because I'm getting stuck.
The problem is to find the parametric equations for the ellipse which made by the intersection of a right circular cylinder of radius c with the plane which intersects the z-axis at point 'a' and the y-axis at point 'b' when t=0.
I think the equation for the cylinder would be
As for the plane I am less sure about the equation. I have points and I could write an equation with one if I had a normal vector to the plane... or the cross product of two vectors in it. Two vectors would be between the points (0, b, 0) and (0, 0, a) and the points (0, b, 0) and (1, 0, a) since x will take on all values. Those vectors are <0, -b, a> and <1, -b, a>
so using the y intercept and the equation of the plane should be or
I get stuck here though... what should I do next? Any help is appreciated.
